A complete Universal system
will consist of the following
An Evaporator Kit that
will include a self-contained air handler that is operated by
electronic servos capable of providing heat cool and defrost (where
applicable) functions. The kit will also
include a set of electrically operated controls (both standard
and optional controls available), all air vents (both standard and optional vents available), with 2 ˝” flexible ducting,
heater control valves, defrost adapters with 2” flexible ducting
(on defrost units)
and a complete wiring harness.
will require removing all original heating and /or A/C components
(boxes, ducting, plenums, cables, and valves from under the dash
area. Any holes left in the firewall, inner fender, and cowl area
that are not utilized during installation must be plugged
or blocked off by the installer. Four lines (2 A/C and 2 heater)
will have to pass through the firewall or inner fender area and
a drain must pass through the firewall behind the evaporator unit.
The unit must be secured under the dash area to the firewall and
dash lip using brackets provided. These brackets are universal
and can be modified for any application. We suggest placing the
unit behind the dash towards the passenger side. You will have remove and cut the glove compartment down to accomplish
this install in most vehicles. The electrical connection is
very simple. One 12 gauge wire goes directly to a battery source
and a purple power lead goes to a key-on source. There are a few
grounds and the rest is plug and play. Complete instructions and schematics take you
through the process step by step.
A Sanden 508 Compressor
that is a universal type. Compressors are available in different
drive types (serpentine or v-belt), different finishes (plain,
polished or black), and with different outlet configurations (top
exit or rear exit)
will require the use of a mounting bracket made to accept
the Sanden 508 compressor. Unfortunately an OE compressor bracket
will not accept these Sanden type compressors without modification.
The R134-A compressors do not have provisions for servicing the
system; you must use the service port fittings in the hose kits.
A compressor mounting bracket
will most likely be available depending on application (We
cover most popular Chevrolet, Ford, Mopar, and Pontiac applications;
You can check for availability on pages
50-56 in our catalog). Since it would be nearly impossible
to develop replacement brackets for every engine ever manufactured;
you may be required to fabricate a mount for your vehicle. If
you choose to use an engine that is not used by mainstream restorers,
you will most likely be fabricating. Although this is the biggest
stumbling block for most people in a custom installation, you
can always choose to use a factory compressor and bracket to operate
the system or maybe obtain a factory bracket to duplicate or modify
it to accept the more reliable and efficient Sanden compressor.
on the most popular applications will simply require removing
factory bolts and replacing with the parts in the kit you will
receive. If you have an application where a bracket must be fabricated,
this is where you must decide if you can accomplish this task
yourself. Metalworking and fabrication skills come into play in
this operation. If you are not comfortable with cutting and welding
metal, you may want to contact one of our dealers in your local
area. If you are ready to tackle the job yourself, the easiest
method to building a replacement bracket is accomplished by finding
an original OE equipment bracket and modifying it to accept the
Sanden. If you are a skilled fabricator, you can simply start
from scratch. We have a universal bracket (part # 15115-VUB) that
can help you accomplish this.
You must remember that cars without factory air will require
pulleys that can accept enough belts to drive all the components.
Often the alternator can be driven off of the Sanden compressor
if you have the room on the same side of the motor.
Universal hose kit that will include three hoses in various
lengths, two A/C bulkhead fittings, and two compressor fittings
with service ports. There will be enough fittings included to
complete the typical installation. The hose kits are sold with
or without a drier and are compatible with our larger decorative
of a universal hose kit
will require you to cut the hoses to length and have the
ends crimped onto them after you have determined the proper fitting
orientation. Usually a local NAPA Autoparts or a local air conditioning
shop will crimp the fittings for you for a small fee. If you cannot
locate someone in your area, we will crimp them for you and you
will only pay for the return freight charges. Vintage Air can also custom fabricate hardlines
to your specifications or you can purchase our “U-Bend-Em” hardlines
that are pre-swedged with the ends and can be easily bent using
common hand tools.
A Condenser will be
sized according to the area in front of the radiator and the opening
in the core support of the radiator. The correct size is determined
by choosing the condenser that will cover the largest amount of
the fin area in front of the radiator.
of a universal condenser will require you to drill holes in the
core support and to fabricate mounting brackets (a set of universal
brackets are included) The general rule of thumb is to place the condenser in the
opening as close to the radiator as possible without touching
it. The placement depends on the line configuration and any obstructions
that will cause interference.
A Safety Switch will
be offered to safeguard your compressor against failure in case
of a high or low refrigerant pressure condition occurring in the
of a safety switch is advisable anywhere in the # 6 or high-pressure
line. We have driers that have provisions to accept the male safety
switches and adapter fittings that help make the installation
a snap. The switch is then wired between the thermostat and the
compressor. Two models are available: A trinary is used when an
electric fan control is needed and a binary is used when only
the safety functions are needed.
Once the installation is complete
you will have to have the system serviced.
that you seek professional help at this point.
Vintage Air recommends the use of a charging
station when doing any type of service to you’re
A/C system. These machines are more efficient and provide the
highest level of accuracy when charging by volume. R134a should
be charged by volume, not by pressure or sight glass readings.
Using the manifold gauge method worked fine for R12, but R134a
is extremely charge sensitive.
